Iphone – How to retract the Keyboard on touching the UITextView when keyboard is already up

iphoneuitextview

I am writing an application that has a UITextView which allows editing. When a user first touches UITextView, a keyboard shows up and I want to retract that keyboard when user again touches the UITextView e.g. I have entered some data in a textview and with keyboard still showing on the screen I tap on the UITextView which should cause the keyboard to retract.

Is there any way to achive this?

(I'm aware of providing a done button and doing this but I want to achive this by tapping on UITextView itself)

As an aside, I would urge you not to use toggle state elements on the iPhone. It's to easy to double tap in real world use. That is why the Apple apps all use the either the "return" key on the keyboard or the done button.

In the interface you contemplate, the users will find themselves closing and then accidentally reopening the keyboard about 10% of the time or more. It will make your app feel cumbersome and flaky.

Objective-c – How to dismiss keyboard for UITextView with return key

Figured I would post the snippet right here instead:

Make sure you declare support for the UITextViewDelegate protocol.

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {

    if([text isEqualToString:@"\n"]) {
        [textView resignFirstResponder];
        return NO;
    }

    return YES;
}

Swift 4.0 update:

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
    if text == "\n" {
        textView.resignFirstResponder()
        return false
    }
    return true
}

Ios – How to lose margin/padding in UITextView

For iOS 7.0, I've found that the contentInset trick no longer works. This is the code I used to get rid of the margin/padding in iOS 7.

This brings the left edge of the text to the left edge of the container:

textView.textContainer.lineFragmentPadding = 0

This causes the top of the text to align with the top of the container:

textView.textContainerInset = .zero

Both lines are needed to completely remove the margin/padding.
